Description
BACKGROUND
[0001]Technological advances associated with computers, operating systems
and applications have enabled users to interact with systems in a vast
and diverse amount of ways. A user interface can provide textual,
graphical and/or auditory information to the user. In addition, a user
interface can receive and/or solicit input from the user that is utilized
to control or operate a computer and software executing on the computer.
Typically, input can be obtained via a keyboard, mouse, track pad, track
ball, digital pen, and/or touch screen. Further, user interfaces can be
non-interactive such as batch interfaces wherein all input is provided up
front in batch jobs. In addition, interactive user interfaces can range
from simple (e.g., command line interfaces) to complex (e.g., graphical
user interfaces). As interfaces grow in complexity, the functionality and
features provided therein also expands.
[0002]A user often must overcome a learning curve with a user interface
before efficient, productive utilization of the interface can occur.
Moreover, for novel interfaces (e.g., gesture-based, touch-based,
crossing-based, etc.), it can be even more difficult to learn and
understand the mechanisms employable to fully interact with the system.
User interface documentation can be provided in the form of help screens
or user manuals. However, such information is typically provided separate
from the application and/or user interface such that it is difficult to
perceive both simultaneously.
SUMMARY
[0003]The following discloses a simplified summary of the specification in
order to provide a basic understanding of some aspects of the
specification. This summary is not an extensive overview of the
specification. It is intended to neither identify key or critical
elements of the specification nor delineate the scope of the
specification. Its sole purpose is to disclose some concepts of the
specification in a simplified form as a prelude to the more detailed
description that is disclosed later.
[0004]The subject innovation relates to systems and/or methods that
facilitate providing assistance information in situ with a user
interface. Assistance information or tips can overlay the user interface
without disturbing a mode, state or responsiveness of the underlying user
interface. Thus, a user can perceive the tips that convey assistance
information related to features or functionality of the user interface
without having to leave the context of the interface. Self-revelation is
utilized to allow assistance information to appear and/or disappear
automatically based on obtained input information or a context of the
interface and/or user.
[0005]In accordance with an aspect of the disclosure, a tip revelation
system is provided. The system includes a decision component that
ascertains whether to show and/or dismiss tips or tip collections based
upon obtained user input and/or context information. For example, the
decision component can activate a tip related to a marking menu (i.e.,
menu with options positioned at different directions relative to a
central control element) if the decision component senses that the user
is hovering over the marking menu without initiating an option via a
directional gesture with an input device.
[0006]According to another aspect of the disclosure, mechanisms are
provided to enable a user to explicitly show or hide tips and/or tip
collections. In addition, preference data can be persisted such that
particular tips will not be revealed after a user becomes familiar with
the associated features or functionality of the interface. Moreover,
mechanisms are provided to extend gesture-based input to legacy
applications developed without gestures in mind.
[0007]The following description and the annexed drawings set forth certain
illustrative aspects of the specification. These aspects are indicative,
however, of but a few of the various ways in which the principles of the
specification can be employed. Other advantages and novel features of the
specification will become apparent from the following detailed
description of the specification when considered in conjunction with the
drawings.

DETAILED DESCRIPTION
[0020]The claimed subject matter is now described with reference to the
drawings, wherein like reference numerals are used to refer to like
elements throughout. In the following description, for purposes of
explanation, numerous specific details are set forth in order to provide
a thorough understanding of the claimed subject matter. It can be
evident, however, that the claimed subject matter can be practiced
without these specific details. In other instances, well-known structures
and devices are shown in block diagram form in order to facilitate
describing the claimed subject matter.
[0021]As used in this application, the terms "component," "module,"
"system", "interface", or the like are generally intended to refer to a
computer-related entity, either hardware, a combination of hardware and
software, software, or software in execution. For example, a component
can be, but is not limited to being, a process running on a processor, a
processor, an object, an executable, a thread of execution, a program,
and/or a computer. By way of illustration, both an application running on
a controller and the controller can be a component. One or more
components can reside within a process and/or thread of execution and a
component can be localized on one computer and/or distributed between two
or more computers. As another example, an interface can include I/O
components as well as associated processor, application, and/or API
components.
[0022]Furthermore, the claimed subject matter can be implemented as a
method, apparatus, or article of manufacture using standard programming
and/or engineering techniques to produce software, firmware, hardware, or
any combination thereof to control a computer to implement the disclosed
subject matter. The term "article of manufacture" as used herein is
intended to encompass a computer program accessible from any
computer-readable device, carrier, or media. For example, computer
readable media can include but are not limited to magnetic storage
devices (e.g.,
hard disk, floppy disk, magnetic strips . . . ), optical
disks (e.g., compact disk (CD), digital versatile disk (DVD) . . . ),
smart cards, and flash memory devices (e.g., card, stick, key drive . . .
). Additionally it should be appreciated that a carrier wave can be
employed to carry computer-readable electronic data such as those used in
transmitting and receiving electronic mail or in accessing a network such
as the Internet or a local area network (LAN). Of course, those skilled
in the art will recognize many modifications can be made to this
configuration without departing from the scope or spirit of the claimed
subject matter.
[0023]Moreover, the word "exemplary" is used herein to mean serving as an
example, instance, or illustration. Any aspect or design described herein
as "exemplary" is not necessarily to be construed as preferred or
advantageous over other aspects or designs. Rather, use of the word
exemplary is intended to disclose concepts in a concrete fashion. As used
in this application, the term "or" is intended to mean an inclusive "or"
rather than an exclusive "or". That is, unless specified otherwise, or
clear from context, "X employs A or B" is intended to mean any of the
natural inclusive permutations. That is, if X employs A; X employs B; or
X employs both A and B, then "X employs A or B" is satisfied under any of
the foregoing instances. In addition, the articles "a" and "an" as used
in this application and the appended claims should generally be construed
to mean "one or more" unless specified otherwise or clear from context to
be directed to a singular form.
[0024]Now turning to the figures, FIG. 1 illustrates a system 100 that
facilitates self-revelation of help information or aides related to a
user interface. The help information can be tips associated with aspects
of the user interface to explain, demonstrate or otherwise inform a user
of the functionality provided. The system 100 includes an interface
component 102 that obtains input information and outputs assistance
information based at least in part on the obtained input information. In
one embodiment, the interface component 102 generates and displays a
graphical user interface. The input information can be, for example,
interactions of a user with the interface component 102 via an input
device (not shown) such as, but not limited to, a tablet and pen, a touch
screen, a mouse, a touch pad, a track ball, and/or any other suitable
device capable of receiving and/or soliciting user interaction with
respect to an interface. The assistance information can relate to
functionality of the interface component 102 revealed in such a way to
enable a user to easily discover and employ various functional features
via the input device. For example, the assistance information can be a
graphical overlay on the user interface that is displayed associated with
at least a portion of the interface indicating techniques employable with
the portion. In addition, the assistance information can be displayed in
situ with the user interface. In an embodiment, the in situ assistance
information is rendered in a manner distinct from the underlying user
interface to highlight the assistance information as being separate from
the user interface. Furthermore such assistance may be rendered in a
manner that intuitively suggests to the user that the assistance
information consists of illustrative annotations, rather than graphical
controls ("widgets") that are meant to be tapped or otherwise operated
directly.
[0025]Pursuant to an illustration, the interface component 102 can be a
gesture-based interface such as, for example, a pen and tablet interface.
It is to be appreciated and understood that gestures can be movements
associated with commands. Moreover, gestures can be movements that
require a user to provide a motion with an input device to activate the
associated commands. By way of example, in a gesture-based interface, a
user can initiate a scrolling action by motioning the input device in a
circular or spiral pattern. In an embodiment, a gesture can be
characterized by a variety of parameters such as, but not limited to, a
gesture start point, an end point, a track line (e.g., the path of the
gesture movement), a speed of motion and/or any other parameters capable
of distinguishing one gesture from another gesture. It is to also be
appreciated that gestures can be employed in conjunction with a plurality
of interfaces and input devices. For example, a mouse-based interface can
be employed wherein a user motions the mouse cursor in accordance with a
gesture to initiate a command. Further, the interface component 102
includes mechanisms to integrate in situ assistance information into
virtually any application wherein assistance information can enable a
user to discover, learn and employ features of the application user
interface.
[0026]The system 100 can also include a decision component 104 that
determines the in situ assistance information output by the interface
component 102. The decision component 104 analyzes the input information
obtained by the interface component 102 to evaluate whether to display a
tip and/or a collection of tips in situ with the user interface. In
addition, the decision component 104 takes into account context
information such as a state of underlying interface elements (e.g., user
interface controls), screen dialogs currently in use, a current mode of
the interface, a state of the user and/or any other information suitable
for a determination of whether to reveal tips. For example, a user,
utilizing an input device, can hover in proximity to a particular
interface element. From the hovering, the decision component 104 can
infer that the user is unsure how to activate a desired feature.
Accordingly, the decision component 104 can determine that a tip
associated with the particular interface elements should be displayed to
the user in situ with the interface element. Moreover, the decision
component 104 can ascertain whether currently displayed tips and/or tip
collections should be dismissed or hidden based upon consideration of the
input information and/or context information. The decision component 104
can establish if tips and/or tip collections require adjusting or
rearranging is response to a user moving and/or resizing underlying user
interface elements.
[0027]FIG. 2 illustrates a system 200 that facilitates providing in situ
tips associated with a user interface. The system 200 can include the
decision component 104 that determines whether tips and/or tip
collections should be displayed in situ with a user interface provided by
interface component 102. In addition, the decision component 104 can
establish which tips, tip collections, and/or tips within a tip
collection should be revealed based upon the input information, context
information, and/or history information associated with a user.
Furthermore decision component 104 may employ information about the
constraints of the device's screen size such that some tips are elided,
modified, or show in different relative locations to accommodate small
screen devices. The decision component also takes into account events
such as moving or resizing the underlying applications, or changing the
screen orientation, to correctly display in situ tips.
[0028]The interface component 102 can include an input component 202 that
collects input information from a user (not shown). In addition, the
interface component 102 can include user interface (UI) controls 204. The
input component 202 can employ one or more controls among UI controls 204
to gather, solicit and/or receive input information from a user. UI
controls 204 are interface elements utilized by a user to interact with a
computing environment. UI controls 204 can include graphical objects such
as, but not limited to, a button, a check box, a text box, a text label,
a slider, a list box, a spinner, a drop-down list, a menu, a toolbar, a
toolbar icon, a ribbon, a combo box (i.e., a text box with attached menu
or list box), an icon, a tree view, a grid view, a tab, a scrollbar, a
status bar, a progress bar and/or any other element capable of
facilitating user interaction. In addition, UI controls 204 can include
interface elements that are collections of other interface elements. For
example, UI controls 204 can include windows, dialog boxes, palette
windows, drawers, heads-up displays and the like. UI controls 204 are
employed to generate a graphical user interface (GUI) provided by the
interface component 102.
[0029]The interface component can also include a tip component 206 that
provides tips or assistance information associated with UI controls 204.
Tip component 206 can include tips and/or tip collections associated with
UI controls of the GUI. The tips and/or tip collections reveal assistance
information that indicate, demonstrate and/or expose functionality of UI
controls 204. The tips provided by tip component 206 can be overlaid on
the underlying GUI. In an embodiment, the tips can be transparent or
partially translucent to enable a user to see the underlying GUI.
Further, the tips can be opaque. In addition, the tips of tip component
206 can present tips in accordance with a style distinct from UI controls
204 so that the tips can be easily distinguished from the underlying
interface while also enabling the tips to be displayed in situ with the
UI controls 204. For example, the tips can include different color
schemes, different typefaces, etc. than employed in the GUI. In an
embodiment, exemplar gestural strokes and descriptions of those gestures
can be presented in an informal handwritten annotation style with yellow
highlighting (similar to marked-up corrections or comments on a real
physical document), such that users intuitively understand the tips to be
informative annotations of the underlying interface.
[0030]The interface component 102 can also include an output component 208
that coordinates construction, generation and/or maintenance of the GUI.
The output component 208 can render UI controls 204 to a display or other
output device (not shown). In addition, the output component 208 can
present tips and/or tip collections supplied from tip component 206 in
situ with UI controls 204 rendered on the output device. The output
component 208 reveals tips based at least in part upon determinations
made by the decision component 104. For example, the decision component
can ascertain to show only a tip overlay associated with a particular
marking menu or gesture-based menu. Accordingly, output component 208
renders the appropriate tip overlay from tip component 206 in conjunction
with the marking menu control of UI controls 204.
[0031]FIG. 3 illustrates a system 300 that facilitates revealing tip or
assistance information associated with a user interface in situ with
controls of the user interface. The system 300 can include the interface
component 102 that obtains input information and outputs in situ
assistance information based at least in part on the obtained input
information. In addition, the system 300 can include a decision component
104 that determines in situ assistance information output by the
interface component 102.
[0032]The interface component 102 can include an output component 208
generates a GUI for an operating system and/or an application. In an
embodiment, the GUI can include UI controls or interface elements as well
tips that convey assistance information. The output component 208
includes a placement component 302 that ascertains placement of a UI
control and/or an associated tip(s) relative to other elements of the
GUI. The placement component 302 facilitates organizing UI controls
and/or tip(s) on an output device such that occlusion of underlying
interface elements is reduced or prevented. For example, it can be
undesirable to have a tip masking an unrelated portion of the user
interface and/or other tips. In an embodiment, the output component 208
can also include a render component 304. The render component 304 draws
or generates a graphical image and/or portion of image to be displayed on
an output device (not shown). The render component 304 can produce
two-dimensional or three-dimensional representations of the UI controls
204 and tips for disclosure on the output device. The render component
304 can produce a final screen image in accordance with the placement
information provided by the placement component 302. Render component 304
may employ window transparency, per-pixel alpha transparency, screen door
transparency, color-key transparency, and/or nonrectangular window
regions that conform to the outline of the tips so as to present a
convincing illusion of an overlay tip window that appears in situ with
other application content. In other embodiments, tips may be drawn
directly in-situ by the host application such that overlay windows are
not needed.
[0033]In addition, the output component 208 can include a fade component
306 that can provide fading aspects to a UI control, tip, or other
portion of the interface. A fade can be a transition from an opaque state
to a non-visible state that traverses varying degrees of translucency and
vice-versa. For example, the fade component 306 can enable an interface
element to fade into visibility, fade out of visibility, explode and fade
out (e.g. a rapid progression to opacity followed by a fade out), or a
combination thereof (e.g., fade out subsequent to a fade in).
Furthermore, fading may be spatially correlated with the position of the
input device or screen cursor, such that tips fade out in proportion to
the distance of the pointer from an interface control. Moreover, the
output component 208 can include an expansion component 308 that
facilitates expanding and contracting a UI control, tip, tip collection
or other portion of the interface out of and into a particular interface
element. For example, the expansion component 308 enables a user to
dismiss a collection of tips such that the displayed tip collection
progressively contracts or shrinks into another UI control or portion of
the interface that can be utilized to show the tip collection at a later
time. Upon reactivation or showing, the tip collection can progressively
expand or grow out of the interface element employed to activate the
tips.
[0034]Moreover, the output component 208 can include an animation
component 308. The animation component 308 can provide video or
animations to various controls or components within a GUI. In an
illustrative instance of a gesture-based interface, the animation
component 308 can provide animations to a tip overlay that demonstrate a
gesture motion or gesture sequence required to activate the feature
associated with the tip overlay. The animation component 308 can
facilitate user understanding of a gesture that can involve a complex
motion or sequence by exhibiting the motion and/or sequence via
animation.
[0035]Referring to FIG. 4, illustrated is a system 400 that facilitates
deciding whether assistance information should be conveyed to a user. The
system 400 includes an interface component 102 that provides a GUI. The
GUI provided by the interface component 102 collects input information
from user via an input device (not shown). In addition, the interface
component 102 provides assistance information related to employing
features of the GUI. The assistance information can be conveyed as tips
overlaid in situ with interactive elements or controls of the GUI. The
system 400 can also include a decision component 104 that determines the
assistance information conveyed to the user via the interface component
102 based at least in part on consideration of the input information or
context information obtained from the interface component 102. In
addition, the decision component 104 can also ascertain if the user
requires assistance information by either inference or direct request
from the user. For example, the system may decide to present tips if the
user taps on an interface control that responds to stroke-based gestures,
since this indicates that the user may not be aware of the gesture
functionality.
[0036]The decision component 104 can include an analysis component 402
that evaluates input information and context information to produce
relevant results. Context information can include such information as a
state of underlying interface elements (e.g., user interface controls),
screen dialogs currently in use, a current mode of the interface, a state
of the user, user preference persisted in a data store (e.g., the system
registry, or settings saved with an individual document) and/or any other
information suitable for determining whether to reveal tips. In addition,
input information can include data provided by a user, user interactions
with the interface, and the like. Pursuant to an illustration, the
analysis component 402 can obtain context information indicating a user
is employing a digital notebook application with a pen-based input
device. In addition, the analysis component 402 can evaluate input
information obtained by the interface component 102 reflecting that the
user is focusing on an icon, tool button or graphical portion such as a
pen tool button employable to select various ink styles for pen-based
input. The input information can indicate that the user is hovering over
the pen tool button for a period without further interaction.
Accordingly, the analysis component 104 can evaluate that the user is
unsure of the appropriate gesture required to select a particular ink
style.
[0037]In addition, the decision component 104 includes a selection
component 404 that ascertains whether assistance information such as a
tip overlay is to be conveyed to the user. The selection component 404
bases the determination at least in part on the evaluation provided by
the analysis component 402. Moreover, the selection component 404 chooses
the type of assistance information. For example, the selection component
404 can choose a tip collection associated with a search panel wherein
the tip collection includes a plurality of tips showing the interactions
required by a user to initiate various functional aspects of the search
panel. In an embodiment, the decision component 104 can include a
resolution component 406 that can be utilized by the analysis component
402 and the selection component 404 to resolve conflicts in the input
information, context information or both. For example, a preference can
be retained by a data store that indicates a user does not wish to see
any assistance information associated with a search panel. A user can
decide to hide search panel tips after the user gains sufficient
familiarity with the gestures. However, the interface component 102 can
obtain input information signifying that the user is hovering over an
element of the search panel. The resolution component 406 can settle the
apparent conflict by suggesting a subset of the tip collection associated
with the search panel and, in particular, the subset can include tips
relevant to the portion of the search panel occupying the user's focus.
[0038]Various inferences or determinations that occur in relation to the
decision component 104 can be processed by an intelligence component 408.
For instance, the intelligence component 408 can infer that a user
requires a refresh of available interface gestures as the user has not
interacted with a particular aspect for a period of time. Moreover, the
artificial intelligence component 408 can make different determinations,
such as determining an appropriate tip collection to display.
[0039]The intelligence component 408 can employ one of numerous
methodologies for learning from data and then drawing inferences and/or
making determinations related to applying a service (e.g., Hidden Markov
Models (HMMs) and related prototypical dependency models, more general
probabilistic graphical models, such as Bayesian networks, e.g., created
by structure search using a Bayesian model score or approximation, linear
classifiers, such as support vector machines (SVMs), non-linear
classifiers, such as methods referred to as "neural network"
methodologies, fuzzy logic methodologies, and other approaches that
perform data fusion, etc.) in accordance with implementing various
automated aspects described herein. Methods also include methods for the
capture of logical relationships such as theorem provers or more
heuristic rule-based expert systems.
[0040]Turning to FIG. 5, an example system 500 is depicted that
facilitates selection and display of assistance information associated
with a GUI with an expanded decision component 104 and selection
component 404. The system 500 can include the interface component 102
that obtains input information and outputs in situ assistance information
based at least in part on the obtained input information. In addition,
the decision component 104 can determine the in situ assistance
information output by the interface component 102. The decision component
104 can include the selection component 404 that ascertains whether
assistance information such as a tip overlay is to be conveyed to the
user.
[0041]The selection component 404 can include a proximity component 502
that determines whether hover-based assistance information should be
displayed. Pursuant to an illustration, the proximity component 502 can
be utilized to decide displaying assistance information in gesture based
interfaces. For example, marking menus are an established pen-input
technique in gesture based interfaces. Marking menus offer menu commands
not in list form as conventional menus do, but rather the menu commands
are placed in different directions (e.g., cardinal compass directions)
around a central interface element or control. A gesture, such as
stroking or flicking, towards the desired command selects it. With
marking menus, a user must remember which direction to gesture in order
to activate a corresponding command. Once the layout becomes familiar,
marking menus provide fast interactions, particularly with pen input.
However, in early learning stages or after long periods of disuse, the
user can require reminding of the commands.
[0042]In an embodiment, a transient semi-transparent overlay can be
provided as an effective hover tip over UI controls such as marking
menus. It is to be appreciated that translucent overlay hover tips can be
employed with other UI controls in addition to marking menus. For
example, hover tips can be utilized in connection with buttons, menus,
embeddable icons (e.g., links to files, web pages, persistent
representations of saved queries, etc.), contextual menus that act on
zero or more objects in a current selection, and the like. According to
an embodiment, the hover tip overlay is a translucent surround about the
central element of a marking menu wherein the tip information that
indicates the commands associated with a given gesture direction is
displayed on top of the surround.
[0043]The proximity component 502 can ascertain when the hover tip overlay
and surround should appear based upon the user hovering an input device
over the control associated with the tip. The translucent surround
feature serves several purposes. For example, the surround separates the
foreground menu layer from the background UI and/or content layers. It is
to be appreciated that the surround may be omitted, but this can cause
greater interference between the layers and/or decrease the utility of
the tip information by reducing the ease at which it can be perceived. In
addition, the translucency of the surround indicates that the tip
information is transient and not directly actionable or interactive.
Moreover, the translucent surround hover tip maintains the context of the
original menu (prior to tip revelation) so the user remains oriented. In
addition, the surround clearly indicates to the user where the tip came
from and maintains visibility of other nearby options if the user wishes
to motion the input device to hover over those options (i.e., nearby
marking menu controls can be perceived through the translucent surround).
This makes it possible for the user to serially inquire each of a series
of marking menus by hovering the input device over each one in turn. In
an embodiment, labels of the tip representing the commands of the marking
menu can be rendered opaque while only the surround remains translucent
so as to increase contrast between the gesture commands the background
layer.
[0044]In another example, the hover tip integrates additional contextual
information, such as, but not limited to, file names, web page titles,
thumbnails, universal resource locators for embedded documents and/or web
pages or the like. Further, in an illustrative instance of a pen-based
input with a digital notebook application, the contextual information can
include recognized handwriting corresponding to ink associated with a UI
control. The added context information can be positioned relative to the
hover tip to avoid overlap with any of the available gestural commands.
In addition, depending on the closeness of a viewable area edge, the
location of the contextual information can be moved to a different
position that will remain visible.
[0045]Pursuant to the marking menu illustration, the interface component
102 and proximity component 502 perform several elements of hover-based
tip activation that can improve usefulness of the tips and, accordingly,
the user's ability to perceive and learn the assistance information
conveyed therein. For example, the interface component 102 can transform
a cursor or other mechanism operable to signify a position on a display.
The interface component 102 transforms a state, shape or graphical form
of the cursor as it moves over a UI control associated with a marking
menu to indicate that a gesture commands are available relative to the UI
control. It is to be appreciated that other transformations are possible.
For example, the cursor can transform to signify the availability of
dragging gestures. Moreover, the proximity component 502 can determine,
based upon the input information, whether a duration of hover perceived
is sufficient to trigger revelation of a hover-based tip. For example,
the hover tip can appear after the input device hovers above the marking
menu for a time-out period to prevent hover tips from spuriously
appearing as the user motions around the interface. In an embodiment, the
time-out period can be 500 to 1000 milliseconds in duration. In addition,
the time-out period can shorten after a first hover tip activates to
enable a user to quickly browse hover tips for a group of marking menus.
Moreover, it is to be appreciated that other input information beyond
hover time can be consider in deciding whether to reveal hover tips. For
example, hover tips can be activated regardless of hover time if the user
motions the input device at a velocity under a threshold. In such a case,
it can be inferred that the user is slowly roaming the interface in
search of a particular feature.
[0046]The proximity component 502 can also determine whether to dismiss a
revealed hover tip. In an embodiment, the hover tip can be dismissed once
the user hovers off the central UI control associated with the hover tip
surround. In addition, for pen-based input devices, the proximity
component 502 can hold the hover tip on the display for a few seconds, or
indefinitely if desired, despite registering an out-of-range event
indicating the user has pulled the pen away from the tablet or touch
screen. For pen-based gesture input on a display tablet, the pen and the
user's hand occludes a portion of the screen. A user can withdraw from
the screen in order to observe the hover tip without obstruction and the
proximity component 502 does not immediately dismiss the hover tip. On
devices without an out-of-range and/or hover capability (e.g.
touch-sensitive Ultra Mobile Personal Computers (UMPC's), or if
out-of-range events cannot be reported to user applications by the device
driver or operating system, the system may observe when the cursor
remains completely motionless and use this to infer that a pointing
device has been withdrawn from the screen surface.
[0047]It is to be appreciated that the proximity component 502 can provide
hover tip determinations to other UI controls beyond marking menus. For
example, hover tips can be employed in conjunction with tab controls
representing pages of a document. When a user hovers over the tab
controls and a lingers for a time-out period, a hover tip explaining
gestures associated with the tab controls can be revealed. For instance,
the hover tip can convey a gesture that demonstrates that pages can be
rearranged by dragging the tab controls via an input device. In another
embodiment, a thumbnail image of a page contents can be shown when a user
hovers of a corresponding page tab.
[0048]According to another embodiment, selection component 404 can employ
a collection component 504 to determine if a tip collection should be
revealed. In situations, assistance information or tips do not exist in
isolation but can form a tip collection providing assistance information
illustrating principal interactive behavior of a functional element or
area of the user interface. For example, a tip collection can convey
assistance information in the form of in situ tips for an entire dialog
box of the user interface. Tip collections enable a user to view a
variety of gestures available in a functional area of the user interface,
discover UI elements that can be used together, and/or extrapolate how
one or more gestures can be combined and/or selected to achieve a desired
goal. While tips are visible, the underlying UI remains active and
capable of interaction. Accordingly, a user can perceive assistance
information while continuing to work.
[0049]The collection component 504 analyzes the input information obtained
by the interface component 102 to evaluate whether to display a tip
and/or a collection of tips in situ with the user interface provided by
interface component 102. In addition, the collection component 504 takes
into account context information such as a state of underlying interface
elements (e.g., user interface controls), screen dialogs currently in
use, a current mode of the interface, a state of the user and/or any
other information suitable for a determination of whether to reveal tips.
The collection component 504 can ascertain whether to dismiss some or all
of the tips currently revealed.
[0050]In an embodiment, the collection component 504 can hide or reveal
tips based on an explicit request from a user. For example, mechanisms
can be provided to a user to hide tips or a subset of tips and/or show
tips or a subset of tips. A hide tips UI control can be provided in
association with a tip collection displayed. The user can interact with
the hide tips UI control to dismiss the tip collection currently visible.
It is to be appreciated that more than one hide tips UI control can be
employed. For example, a plurality of controls can be associated with
different portions or subsets of visible tips. Further, each individual
tip can be associated with a control by which to dismiss the tip.
Moreover, a UI control can be provided to explicitly recall or show tips.
Once the control is activated, the collection component 504 can determine
what tips are to be shown. In addition, separate elements of the user
interface can include an exclusive show tips control for enabling tips on
the separate element alone. The interface component 102 can employ
animations when hiding and showing tips in accordance with determinations
made by the decision component 104. For example, a tip collection can be
animated to emerge and expand from a particular UI control a user can
employ to explicitly activate the tip collection. In addition, the tip
collection can be animated to shrink or contract into the UI control upon
dismissal to inform a user of the control necessary to reactive the tips.
[0051]The collection component 504 and decision component 104 can
communicate with a data store 508 to persist user preferences with regard
to tips and/or tip collections. A control can be provided along with a
tip collection to enable a user to choose to suppress the tip collection
once a user gains familiarity with the underlying UI functionality. A
user can employ the control to indicate that the tip collection should
not appear again even in situations in which the decision component 104
would determine revelation is appropriate. The preference can be
persisted in data store 508. The collection component 504 queries data
store 508 to discover if a preference is retained and suppresses a tip
collection accordingly. The preference can be persisted across
application instances, persisted across the operating system, associated
with a particular user or a particular file, etc.
[0052]It is to be appreciated that the data store 508 can be, for example,
either volatile memory or nonvolatile memory, or can include both
volatile and nonvolatile memory. By way of illustration, and not
limitation, nonvolatile memory can include read only memory (ROM),
programmable ROM (PROM), electrically programmable ROM (EPROM),
electrically erasable programmable ROM (EEPROM), or flash memory.
Volatile memory can include random access memory (RAM), which acts as
external cache memory. By way of illustration and not limitation, RAM is
available in many forms such as static RAM (SRAM), dynamic RAM (DRAM),
synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced
SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), Rambus direct RAM (RDRAM),
direct Rambus dynamic RAM (DRDRAM), and Rambus dynamic RAM (RDRAM). The
data store 508 of the subject systems and methods is intended to
comprise, without being limited to, these and any other suitable types of
memory. In addition, it is to be appreciated that the data store 508 can
be a server, a database, a hard drive, a pen drive, an external hard
drive, a portable
hard drive, and the like.
[0053]In an embodiment, the proximity component 502 and/or the collection
component 504 can determine to reveal a tip and/or tip collection.
Numerous gesture commands can be available to a user relative to a single
region of the user interface. In some situations, gestures commands can
be defined to avoid spatial overlap. However, even in such situations,
numerous tips can overlap each other. The decision component 104 can
include a contention component 506 to resolve multiple overlapping
gestures on a given area of the interface. In an illustrative instance,
when a user selects a lasso selection tool in a digital notebook
application, tips can be revealed in situ that demonstrate various
functional aspects of the lasso selection tool, including gestures
employable via an input device to active respective functional aspects.
The revealed tips can be a collection of commonly utilized aspects, for
example. The tips can be hierarchically organized to signify
dependencies. For example, a gesture employable to drag a selection is
dependent upon a selection being made. Thus, the drag gesture tip can be
shown dependent upon a gesture employable to select an object, portion of
content, etc. In addition, the subset of tips displayed can be only those
with preconditions satisfied. The revealed tips can be static
representations of the respective gestures, or they may contain images of
or be drawn in reference to the current content and objects in a user's
document. In addition, the revealed tips can be videos and/or animations
of the gestures being drawn.
[0054]FIGS. 6-10 illustrate methodologies and/or flow diagrams in
accordance with the claimed subject matter. For purposes of simplicity of
explanation, methodologies that can be implemented in accordance with the
disclosed subject matter were shown and described as a series of blocks.
However, it is to be understood and appreciated that the claimed subject
matter is not limited by the order of the blocks, as some blocks can
occur in different orders and/or concurrently with other blocks from what
is depicted and described herein. Moreover, not all illustrated blocks
can be required to implement the methodologies described hereinafter.
Additionally, it should be further appreciated that the methodologies
disclosed throughout this specification are capable of being stored on an
article of manufacture to facilitate transporting and transferring such
methodologies to computers. The term article of manufacture, as used, is
intended to encompass a computer program accessible from any
computer-readable device, carrier, or media.
[0055]FIG. 6 illustrates a method 600 that facilitates providing
assistance information in situ with a user interface. The method 600
commences at reference numeral 602 where input information and/or context
information is obtained. The input information can include information
regarding interactions of a user with the user interface. The context
information can include a state of underlying interface elements (e.g.,
user interface controls), screen dialogs currently in use, a current mode
of the interface, a state of the user and/or any other information
suitable for a determination of whether to reveal tips. At reference
numeral 604, the input information and/or context information is analyzed
to evaluate or infer a state of the user with respect to the user
interface. For example, it can ascertained based upon the input
information and/or context information that the user is unsure what
interactions are required to bring about particular functionality of an
application. At reference numeral 606, candidate tip information is
selected. The candidate tip information can be determined based at least
in part on the analysis of the input and/or context information. For
example, the input information can indicate that a user is hovering over
a marking menu UI control. The candidate tip information can include a
hover tip conveying available gesture commands associated with the UI
control. At reference numeral 608, the candidate tip information is
revealed in situ with the interface. Pursuant to an example, the tip
information can be revealed as an overlay to the associated UI control.
[0056]FIG. 7 illustrates an example method 700 that facilitates employing
in situ assistance information in connection with gesture-based
interfaces. The method 700 can be employed with a user interface to aid
users with learning and/or remembering functional aspects of the
interface. For example, the method 700 can be utilized to provide in situ
interface tips associated with marking menus. Marking menus are an
established pen-input technique in gesture-based interfaces. Marking
menus offer menu commands not in list form as conventional menus do, but
rather the menu commands are placed in different directions (e.g.,
cardinal compass directions) around a central interface element or
control. A gesture, such as stroking or flicking, towards the desired
command selects it.
[0057]The method 700 commences at reference numeral 702 where proximity
information is collected. Proximity information can include, for example,
indications that a user is maintaining proximity to a marking menu
central control via an input device. For example, with pen-based gesture
interfaces, the user can hover the pen over the marking menu control. At
reference numeral 704, tip information is revealed in response to the
proximity information. In an illustrative instance, the tip information
can include a translucent in situ overlay providing an explanation of the
gesture commands employable with the marking menu control. At reference
numeral 706, additional input information is obtained. At reference
numeral 708, a determination is made as to whether the input information
obtained indicates a tap down. A tap down event may register if a user
touches the central control of marking menu with an input device for a
given period of time (e.g., a third of a second). If the input
information is a tap down event, the method proceeds with reference
numeral 710 where the tip information can solidify from translucent to
opaque.
[0058]If No, the method proceeds to reference numeral 712 where a
determination is made as to whether the input information indicates a
hover away event. For example, a user can hover outside the central
control element of a marking menu to achieve a hover away event. If Yes,
the tip information is hidden at reference numeral 714. In an embodiment,
the tip hide on hover away discourages the user from selecting the
displayed commands with the input device rather than perform the
associated gesture. In another embodiment, the user may hover to the
desired function and then tap on the hover overlay itself as an
alternative to employing the actual gesture to activate the command. If
No, the method proceeds to reference numeral 716.
[0059]At reference numeral 716, a determination is made as to whether the
input information signifies a hover off. In an illustrative instance of
pen-based input, a user's hand occludes a portion of the screen. Thus,
the user can remove the pen from the screen in order to view the
displayed tip information. This can trigger a hover off event. If the
input information indicates a hover off event, the method proceeds to
reference numeral 718 where the revealed tip information holds on the
display to enable a user to perceive it. If the input is not a hover off
event, the method proceeds to reference numeral 720. At 720, it is
ascertained if the input information indicates marking input or a
gesture. If Yes, the method proceeds to reference numeral 722 where the
command on the tip information selected by the marking input is
highlighted. For example, the selected command can explode and fade. In
another embodiment, the command can just appear with a subsequent fade.
In addition, the command can appear and then vanish after a specified
time (e.g., 1 second). If the input information is not marking input, the
method proceeds back to reference numeral 706 where additional input
information is collected.
[0060]FIG. 8 illustrates a method 800 that facilitates managing tip
collections in situ with a user interface. In situations, assistance
information or tips do not exist in isolation but can form a tip
collection providing assistance information illustrating principal
interactive behavior of a functional element or area of the user
interface. For example, a tip collection can convey assistance
information in the form of in situ tips for an entire dialog box of the
user interface. Tip collections enable a user to view a variety of
gestures available in a functional area of the user interface, discover
UI elements that can be used together, and/or extrapolate how one or more
gestures can be combined and/or selected to achieve a desired goal. At
reference numeral 802, a tip collection is revealed. At reference numeral
804, input information is collected. At 806, a determination is made as
to whether the input information relates to showing or hiding tips. For
example, a user can hover over a control associated with hover tips. The
hover action can trigger additional tips. In addition, a user can
explicitly show or hide tips and/or tip collections. If the input
information indicates show, the method proceeds to reference numeral 808
where additional tips are revealed in accordance the input information.
At 810, background tips previously revealed are dimmed (or removed
completely) so as to not interfere with user perception of the additional
tips. If hide was signified from the input information, the revealed tip
collection is dismissed at reference numeral 812. At 814, the hidden
status is retained such the tip collection does not reveal again unless
explicitly requested by a user.
[0061]Turning now to FIG. 9, a method 900 is illustrated that facilitates
providing assistance information for multiple overlapping gesture inputs
in a gesture-based user interface. A variety of gestures can be
employable from a given area of the user interface. The gestures can
spatially overlap such that it becomes difficult to display in situ tip
information. The method 900 commences at reference numeral 902 where a
need to reveal tip information is identified. For example, a user may
hover over a portion of the user interface actionable with gestures. In
addition, a need can be identified when a user activates an aspect of an
application for the first time. At reference numeral 904, a tip
collection is identified. For example, in the case of a single hover
control, the tip collection can include a hover overlay for that control.
In addition, a plurality of tip can be selected when a dialog is
activated in the user interface. Moreover, a tip collection including
exemplary or common gestures can be selected. At reference numeral 906, a
disclosure mechanism is selected. For example, a series of frames
including static representations of multiple overlapping gestures can be
employed. In addition, the tips can be videos or animations of the
gestures being drawn. At reference numeral 908, the selected tip
collection is communicated in accordance the determined disclosure
mechanism.
[0062]FIG. 10 illustrates an example method 1000 that facilitates
extending gesture input to preexisting applications. For example, some
applications, such as a digital notebook application, fully employ
gestures. However, some applications do not employ any gestures by
default. At reference numeral 1002, a floating tool palette is associated
with an application. In an illustrative instance, the floating tool
palette can be a translucent overlay placed in a conspicuous location on
the associated application or window. In addition, the floating tool
palette can solidify (e.g., becomes opaque) as a user hovers over the
palette. At reference numeral 1004, input entered via the palette is
captured. For example, a user can activate the palette control and
initiate a gesture. In the case of pen-based input, a user can touch the
pen down on to the palette to initiate a gesture. As long as the gesture
initiates within the tool palette, the gesture motion can escape the
bounds of the tool palette and the input is still captured. At reference
numeral 1006, event data is generated from the gesture information. For
example, if a gesture is a scrolling gesture, scrolling event data is
generated. At reference numeral 1008, the generated event data is
forwarded to the associated application. Thus, the gesture motion
performs an input operation on a user interface not originally
implemented with gesture-based commands. This shows how an overlay can be
used not only to reveal gesture functionality, but also to directly
support gesture functionality on top of applications that normally would
not implement such gestures. It also shows how gestural tips may
themselves offer interactive feedback in response to user movement of a
pointing device, rather than providing just information displays.
[0063]In order to provide a context for the various aspects of the
disclosed subject matter, FIGS. 11 and 12 as well as the following
discussion are intended to provide a brief, general description of a
suitable environment in which the various aspects of the disclosed
subject matter can be implemented. While the subject matter has been
described above in the general context of computer-executable
instructions of a program that runs on one or more computers, those
skilled in the art will recognize that the subject matter described
herein also can be implemented in combination with other program modules.
Generally, program modules include routines, programs, components, data
structures, etc. that perform particular tasks and/or implement
particular abstract data types. Moreover, those skilled in the art will
appreciate that the inventive methods can be practiced with other
computer system configurations, including single-processor,
multiprocessor or multi-core processor computer systems, mini-computing
devices, mainframe computers, as well as personal computers, hand-held
computing devices (e.g., personal digital assistant (PDA), phone, watch .
. . ), microprocessor-based or programmable consumer or industrial
electronics, and the like. The illustrated aspects can also be practiced
in distributed computing environments where tasks are performed by remote
processing devices that are linked through a communications network.
However, some, if not all aspects of the claimed subject matter can be
practiced on stand-alone computers. In a distributed computing
environment, program modules can be located in both local and remote
memory storage devices.
[0064]Referring now to FIG. 11, there is illustrated a schematic block
diagram of a computing environment 1100 in accordance with the subject
specification. The system 1100 includes one or more client(s) 1102. The
client(s) 1102 can be hardware and/or software (e.g., threads, processes,
computing devices). The client(s) 1102 can house cookie(s) and/or
associated contextual information by employing the specification, for
example.
[0065]The system 1100 also includes one or more server(s) 1104. The
server(s) 1104 can also be hardware and/or software (e.g., threads,
processes, computing devices). The servers 1104 can house threads to
perform transformations by employing the specification, for example. One
possible communication between a client 1102 and a server 1104 can be in
the form of a data packet adapted to be transmitted between two or more
computer processes. The data packet can include a cookie and/or
associated contextual information, for example. The system 1100 includes
a communication framework 1106 (e.g., a global communication network such
as the Internet) that can be employed to facilitate communications
between the client(s) 1102 and the server(s) 1104.
[0066]Communications can be facilitated via a wired (including optical
fiber) and/or wireless technology. The client(s) 1102 are operatively
connected to one or more client data store(s) 1108 that can be employed
to store information local to the client(s) 1102 (e.g., cookie(s) and/or
associated contextual information). Similarly, the server(s) 1104 are
operatively connected to one or more server data store(s) 1110 that can
be employed to store information local to the servers 1104.
[0067]Referring now to FIG. 12, there is illustrated a block diagram of a
computer operable to execute the disclosed architecture. In order to
provide additional context for various aspects of the subject
specification, FIG. 12 and the following discussion are intended to
provide a brief, general description of a suitable computing environment
1200 in which the various aspects of the specification can be
implemented. While the specification has been described above in the
general context of computer-executable instructions that can run on one
or more computers, those skilled in the art will recognize that the
specification also can be implemented in combination with other program
modules and/or as a combination of hardware and software.
[0068]Generally, program modules include routines, programs, components,
data structures, etc., that perform particular tasks or implement
particular abstract data types. Moreover, those skilled in the art will
appreciate that the inventive methods can be practiced with other
computer system configurations, including single-processor or
multiprocessor computer systems, minicomputers, mainframe computers, as
well as personal computers, hand-held computing devices,
microprocessor-based or programmable consumer electronics, and the like,
each of which can be operatively coupled to one or more associated
devices.
[0069]The illustrated aspects of the specification can also be practiced
in distributed computing environments where certain tasks are performed
by remote processing devices that are linked through a communications
network. In a distributed computing environment, program modules can be
located in both local and remote memory storage devices.
[0070]A computer typically includes a variety of computer-readable media.
Computer-readable media can be any available media that can be accessed
by the computer and includes both volatile and nonvolatile media,
removable and non-removable media. By way of example, and not limitation,
computer-readable media can comprise computer storage media and
communication media. Computer storage media includes volatile and
nonvolatile, removable and non-removable media implemented in any method
or technology for storage of information such as computer-readable
instructions, data structures, program modules or other data. Computer
storage media includes, but is not limited to, RAM, ROM, EEPROM, flash
memory or other memory technology, CD-ROM, digital versatile disk (DVD)
or other optical disk storage, magnetic cas
settes, magnetic tape,
magnetic disk storage or other magnetic storage devices, or any other
medium which can be used to store the desired information and which can
be accessed by the computer.
[0071]Communication media typically embodies computer-readable
instructions, data structures, program modules or other data in a
modulated data signal such as a carrier wave or other transport
mechanism, and includes any information delivery media. The term
"modulated data signal" means a signal that has one or more of its
characteristics set or changed in such a manner as to encode information
in the signal. By way of example, and not limitation, communication media
includes wired media such as a wired network or direct-wired connection,
and wireless media such as acoustic, RF, infrared and other wireless
media. Combinations of the any of the above should also be included
within the scope of computer-readable media.
[0072]With reference again to FIG. 12, the example environment 1200 for
implementing various aspects of the specification includes a computer
1202, the computer 1202 including a processing unit 1204, a system memory
1206 and a system bus 1208. The system bus 1208 couples system components
including, but not limited to, the system memory 1206 to the processing
unit 1204. The processing unit 1204 can be any of various commercially
available processors. Dual microprocessors and other multi-processor
architectures can also be employed as the processing unit 1204.
[0073]The system bus 1208 can be any of several types of bus structure
that can further interconnect to a memory bus (with or without a memory
controller), a peripheral bus, and a local bus using any of a variety of
commercially available bus architectures. The system memory 1206 includes
read-only memory (ROM) 1210 and random access memory (RAM) 1212. A basic
input/output system (BIOS) is stored in a non-volatile memory 1210 such
as ROM, EPROM, EEPROM, which BIOS contains the basic routines that help
to transfer information between elements within the computer 1202, such
as during start-up. The RAM 1212 can also include a high-speed RAM such
as static RAM for caching data.
[0074]The computer 1202 further includes an internal hard disk drive (HDD)
1214 (e.g., EIDE, SATA), which internal
hard disk drive 1214 can also be
configured for external use in a suitable chassis (not shown), a magnetic
floppy disk drive (FDD) 1216, (e.g., to read from or write to a removable
diskette 1218) and an optical disk drive 1220, (e.g., reading a CD-ROM
disk 1222 or, to read from or write to other high capacity optical media
such as the DVD). The
hard disk drive 1214, magnetic disk drive 1216 and
optical disk drive 1220 can be connected to the system bus 1208 by a hard
disk drive interface 1224, a magnetic disk drive interface 1226 and an
optical drive interface 1228, respectively. The interface 1224 for
external drive implementations includes at least one or both of Universal
Serial Bus (USB) and IEEE 1394 interface technologies. Other external
drive connection technologies are within contemplation of the subject
specification.
[0075]The drives and their associated computer-readable media provide
nonvolatile storage of data, data structures, computer-executable
instructions, and so forth. For the computer 1202, the drives and media
accommodate the storage of any data in a suitable digital format.
Although the description of computer-readable media above refers to a
HDD, a removable magnetic diskette, and a removable optical media such as
a CD or DVD, it should be appreciated by those skilled in the art that
other types of media which are readable by a computer, such as zip
drives, magnetic cassettes, flash memory cards, cartridges, and the like,
can also be used in the example operating environment, and further, that
any such media can contain computer-executable instructions for
performing the methods of the specification.
[0076]A number of program modules can be stored in the drives and RAM
1212, including an operating system 1230, one or more application
programs 1232, other program modules 1234 and program data 1236. All or
portions of the operating system, applications, modules, and/or data can
also be cached in the RAM 1212. It is appreciated that the specification
can be implemented with various commercially available operating systems
or combinations of operating systems.
[0077]A user can enter commands and information into the computer 1202
through one or more wired/wireless input devices, e.g., a keyboard 1238
and a pointing device, such as a mouse 1240. Other input devices (not
shown) can include a microphone, an IR remote control, a joystick, a game
pad, a stylus pen, touch screen, or the like. These and other input
devices are often connected to the processing unit 1204 through an input
device interface 1242 that is coupled to the system bus 1208, but can be
connected by other interfaces, such as a parallel port, an IEEE 1394
serial port, a game port, a USB port, an IR interface, etc.
[0078]A monitor 1244 or other type of display device is also connected to
the system bus 1208 via an interface, such as a video adapter 1246. In
addition to the monitor 1244, a computer typically includes other
peripheral output devices (not shown), such as speakers, printers, etc.
[0079]The computer 1202 can operate in a networked environment using
logical connections via wired and/or wireless communications to one or
more remote computers, such as a remote computer(s) 1248. The remote
computer(s) 1248 can be a workstation, a server computer, a router, a
personal computer, portable computer, microprocessor-based entertainment
appliance, a peer device or other common network node, and typically
includes many or all of the elements described relative to the computer
1202, although, for purposes of brevity, only a memory/storage device
1250 is illustrated. The logical connections depicted include
wired/wireless connectivity to a local area network (LAN) 1252 and/or
larger networks, e.g., a wide area network (WAN) 1254. Such LAN and WAN
networking environments are commonplace in offices and companies, and
facilitate enterprise-wide computer networks, such as intranets, all of
which can connect to a global communications network, e.g., the Internet.
[0080]When used in a LAN networking environment, the computer 1202 is
connected to the local network 1252 through a wired and/or wireless
communication network interface or adapter 1256. The adapter 1256 can
facilitate wired or wireless communication to the LAN 1252, which can
also include a wireless access point disposed thereon for communicating
with the wireless adapter 1256.
[0081]When used in a WAN networking environment, the computer 1202 can
include a
modem 1258, or is connected to a communications server on the
WAN 1254, or has other means for establishing communications over the WAN
1254, such as by way of the Internet. The modem 1258, which can be
internal or external and a wired or wireless device, is connected to the
system bus 1208 via the serial port interface 1242. In a networked
environment, program modules depicted relative to the computer 1202, or
portions thereof, can be stored in the remote memory/storage device 1250.
It will be appreciated that the network connections shown are example and
other means of establishing a communications link between the computers
can be used.
[0082]The computer 1202 is operable to communicate with any wireless
devices or entities operatively disposed in wireless communication, e.g.,
a printer, scanner, desktop and/or portable computer, portable data
assistant, communications satellite, any piece of equipment or location
associated with a wirelessly detectable tag (e.g., a kiosk, news stand,
restroom), and telephone. This includes at least Wi-Fi and Bluetooth.TM.
wireless technologies. Thus, the communication can be a predefined
structure as with a conventional network or simply an ad hoc
communication between at least two devices.
[0083]Wi-Fi, or Wireless Fidelity, allows connection to the Internet from
a couch at home, a bed in a hotel room, or a conference room at work,
without wires. Wi-Fi is a wireless technology similar to that used in a
cell phone that enables such devices, e.g., computers, to send and
receive data indoors and out; anywhere within the range of a base
station. Wi-Fi networks use radio technologies called IEEE 802.11(a, b,
g, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi
network can be used to connect computers to each other, to the Internet,
and to wired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks
operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps
(802.11a) or 54 Mbps (802.11b) data rate, for example, or with products
that contain both bands (dual band), so the networks can provide
real-world performance similar to the basic 10 BaseT wired Ethernet
networks used in many offices.
[0084]What has been described above includes examples of the subject
specification. It is, of course, not possible to describe every
conceivable combination of components or methodologies for purposes of
describing the subject specification, but one of ordinary skill in the
art can recognize that many further combinations and permutations of the
subject specification are possible. Accordingly, the subject
specification is intended to embrace all such alterations, modifications
and variations that fall within the spirit and scope of the appended
claims. Furthermore, to the extent that the term "includes" is used in
either the detailed description or the claims, such term is intended to
be inclusive in a manner similar to the term "comprising" as "comprising"
is interpreted when employed as a transitional word in a claim.
